I test drove 6mt m3 ,it's not much different from the bmw manual of old,the only difference is the light clutchpedal. I drive a MT z3 for 12 yrs now and bmw MT have always been notch and engagement pt is always high,you get use to it,shift it like you mean it and give it a bit of rev to smoothen things.

Go to those old bmw forums and this has been a complaint for years,changing my z3 trans fluid to royal purple which is more slippery than what was in there and getting a short shifter helped a lot.

By the way will be joining you privilege few soon,picking my ED M3 6mt in April.
